There are better scorers and rebounders in college basketball. There are much more versatile players. There are plenty of better defenders.

But when it comes to steady production, nobody does it better than LSU junior Glen Davis.

The past three weeks provide a great example. Davis - who is coming off a season where he racked up 19 double-doubles - put together double-doubles in each of his last four games.

Davis scored between 20-24 points and grabbed between 10-13 rebounds in each of the games.

Those consistent numbers weren't coming against a bunch of cupcakes at home either. Two of the games were on the road, where the Tigers pulled out seven-point wins at Tulane and Oregon State. Another was at a neutral site where the Tigers fell in overtime by one point to Texas in Houston. The other came in a 12-point win over then-No. 6 Texas A&M.

Arizona's Ivan Radenovic moved up to No. 7 in the center rankings, thanks to his second double-double in three games. Radenovic, who leads the 8-1 Wildcats with 17.4 points and 7.8 rebounds a game, scored 16 points and corralled 11 rebounds in an 87-62 win over Houston.

None of the other top spots changed, but Alabama's Jermareo Davidson did slide up to No. 2 in the power forward rankings. With star point guard Ronald Steele limited to just four minutes against Southern Miss because of a sprained ankle, Davidson stepped up and carried the Tide (9-1) to a 77-64 win in Mobile, Ala. The big man scored a game-high 25 points and hauled in 11 boards.

Arizona's Marcus Williams took over the No. 2 spot among the shooting guards. Williams followed the best game of his career – a 21-point, 16-rebound outing at San Diego State – by scoring 15 points and grabbing 12 boards against Houston.

In just 16 minutes of playing time in the Orange's win over Baylor, Harris scored 15 points, had eight rebounds and dished out four assists. Mejia, who has been inconsistent at times, is heating up again. He scored 23 points and 22 points in the Blue Demons' wins over Wake Forest and Rhode Island.

Memphis' Chris Douglas-Roberts continues to make a steady climb up the small forward rankings, moving up to No. 12. Douglas-Roberts scored a career-high 28 points in a win over Austin Peay.

A pair of freshmen moved up in the point guard rankings. Ohio State's Mike Conley Jr. (No. 14) and Texas' D.J. Augustin (No. 15) are playing more like veterans than rookies.

Conley owns a 2.9-to-1 assist-to-turnover ratio and is averaging 6.5 assists a game. Augustin is averaging 6.2 assists a game and has emerged as a major scoring threat as of late, combining for 49 points in his last two games.

We will continue to update the power rankings weekly throughout the season. For our purposes, the power rankings will reflect those games played Tuesday through Monday.

The rating of a player and coach can fluctuate each week, but the power rankings measure their overall careers as well as their most recent performances.

By the end of the season, our power rankings should provide an accurate indicator of which players were the best at their respective positions.
